How the kettle got its whistle
(Phys.org) —Researchers have finally worked out where the noise that makes kettles whistle actually comes from – a problem which has puzzled scientists for more than 100 years.
New flow battery could enable cheaper, more efficient energy storage
MIT researchers have engineered a new rechargeable flow battery that doesn't rely on expensive membranes to generate and store electricity. The device, they say, may one day enable cheaper, large-scale energy ...
Heat flow from Earth's mantle contributes to Greenland ice melting
The Greenland ice sheet is melting from below, caused by a high heat flow from the mantle into the lithosphere. This influence is very variable spatially and has its origin in an exceptionally thin lithosphere. ...
New LED streetlight design curbs light pollution
Streetlights illuminate the night, shining upon roadways and sidewalks across the world, but these ubiquitous elements of the urban environment are notoriously inefficient and major contributors to light ...
Surprising turns in magnetic thin films could lead to better data storage
A magnetic phenomenon newly discovered by MIT researchers could lead to much faster, denser and more energy-efficient chips for memory and computation.
Geoscientist finds beavers play a role in climate change
Try clapping your wet hands: A physics lesson from Virginia Tech engineers
Sunny Jung continues to redefine the views on the laws of physics, and in doing so, impacts the research on topics as varied as drug delivery methods to fuel efficiency.
Graphene joins the race to redefine the ampere
A new joint innovation by the National Physical Laboratory (NPL) and the University of Cambridge could pave the way for redefining the ampere in terms of fundamental constants of physics. The world's first ...
Scientists identify a mathematical 'crystal ball' that may predict calamities
Neuroscientists have come up with a mathematical equation that may help predict calamities such as financial crashes in economic systems and epileptic seizures in the brain.
Rising temperatures challenge Salt Lake City's water supply
In an example of the challenges water-strapped Western cities will face in a warming world, new research shows that every degree Fahrenheit of warming in the Salt Lake City region could mean a 1.8 to 6.5 percent drop in the ...
